Question

我正在使用carrierwave作为我在Rails项目中上传图片的宝石，它可以在除Android以外的所有设备上正常工作，每当我从Android设备上传图像然后它旋转90度。

这些是用于上传图片的宝石：

gem 'rmagick'
gem 'carrierwave'

以下是avatar_uploader.rb

的代码

# encoding: utf-8

class AvatarUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  version :thumb, :if => :image? do
    process :crop
    resize_to_fill(100, 100)
  end

  version :large, :if => :image? do
    resize_to_limit(600, 600)
  end

  def crop
    if model.crop_x.present?
      resize_to_limit(600, 600)
      manipulate! do |img|
        x = model.crop_x.to_i
        y = model.crop_y.to_i
        w = model.crop_w.to_i
        h = model.crop_h.to_i
        img.crop!(x, y, w, h)
      end
    end
  end

    protected

    def image?(new_file)
        new_file.content_type.include? 'image'
    end

end

最后我在这里得到了解决方案https://stackoverflow.com/a/18541893，

这是我为修复它所做的更改：

在avatar_uploader.rb中添加了此内容：

def auto_orient
    manipulate! do |img|
      img = img.auto_orient
    end
end

并将其用作：

  version :thumb, :if => :image? do
    process :auto_orient      // here it is used
    process :crop
    resize_to_fill(100, 100)
  end

  version :large, :if => :image? do
    process :auto_orient      // here it is used
    resize_to_limit(600, 600)
  end

那就是：）
